Lantheus Holdings, Inc. ("Lantheus") (NASDAQ:LNTH), the leading radiopharmaceutical-focused company committed to enabling clinicians to Find, Fight and Follow disease to deliver better patient outcomes, today announced its acquisition of the global rights of Life Molecular Imaging's ("Life Molecular") RM2, targeting the gastrin-releasing peptide receptor (GRPR), including the associated novel, clinical-stage radiotherapeutic and radiodiagnostic pair, referred to as 177Lu-DOTA-RM2 and 68Ga-DOTA-RM2. This acquisition strengthens Lantheus' presence in prostate cancer and expands its pipeline to include breast and other cancers. The agreement includes global rights1 to this radiotheranostic pair for an upfront payment of $35 million and potential regulatory milestone payments plus royalties.

Lantheus' acquisition of worldwide rights to 177Lu-DOTA-RM2 and 68Ga-DOTA-RM2 underscores its dedication to pioneering cancer care and marks a significant step towards addressing unmet medical needs in prostate and breast cancer treatment. RM2 was discovered at the Universities Bern and Basel and development was originally performed by Bayer Pharma AG. It was subsequently licensed to Life Molecular. 68Ga-DOTA-RM2 targets cancers overexpressing GRPR, such as prostate, breast, lung, pancreatic, colorectal, gastric and ovarian cancers and has been extensively studied in various tumor types. First-in-human dosimetry showed a favorable safety and dosimetry profile and confirmed preclinical data demonstrating dose-dependent efficacy of 177Lu-DOTA-RM2. Lantheus intends to begin a Phase 1/2a study with 177Lu-DOTA-RM2 in prostate cancer patients in 2025. 68Ga-DOTA-RM2 will be used as a companion diagnostic.
